Association Between Social Networking Site Use Intensity and Depression Among Chinese Pregnant Women: Cross-sectional Study.

BACKGROUND: Despite extensive debates about the mental health impacts of the use of social networking sites (SNSs), including WeChat, the association and mechanisms between social interaction of WeChat use intensity and antenatal depression are unclear. OBJECTIVE: We aimed to test the mediating roles of upward social comparison on social interaction of WeChat and rumination in the association between social interaction of WeChat use intensity and antenatal depression. METHODS: A cross-sectional survey was conducted in four hospitals with the self-reported measures of social interaction of WeChat use intensity, upward social comparison on social interaction of WeChat, rumination, antenatal depression, and control variables. The mediation analysis was performed through Model 6 from the PROCESS macro 4.0 in SPSS 26. RESULTS: Results from 2661 participants showed that antenatal depression was unrelated to social interaction of WeChat use intensity (P=.54), but was significantly positively related to the attitude toward social interaction of WeChat (P=.01). The direct effect of attitude toward social interaction of WeChat use on antenatal depression was not statistically significant (ß=-.03, P=.05). The results supported an indirect relationship between attitude toward social interaction of WeChat use and antenatal depression via (1) upward social comparison on social interaction of WeChat (indirect effect value=0.04, 95% CI 0.03 to 0.06); (2) rumination (indirect effect value=-0.02, 95% CI -0.04 to -0.01); and (3) upward social comparison on social interaction of WeChat and rumination in sequence (indirect effect value=0.07, 95% CI 0.06 to 0.08). CONCLUSIONS: Our findings highlight the necessity of focusing on attitudes toward SNS use, and the importance of upward social comparison and rumination in understanding the effect of SNS use on antenatal depression.

Status and influencing factors of nursing and midwifery professionals' core competence- a cross sectional study.

OBJECTIVES: This study aims to understand the current situation and multiple factors affecting the core competence specializing in the maternal, neonatal and under-five nursing in China. BACKGROUND: Highly skilled nurses and midwives are essential worldwide for achieving the Sustainable Development Goals, especially in low- and middle-income countries like China, due to the overwhelming COVID-19 crisis. METHOD: The 890 nurses and midwives from 12 hospitals were investigated in this cross-sectional study, with two questionnaires: the sociodemographic information and competency inventory for the registered nurses. RESULTS: The participants reported a mean total score of 193.78 (±42.19) out of 220 and lowest in critical thinking and research ability (3.01 ± 0.82). The professional title, level, marital status, relationship quality, highest qualification, experience in specialist nurse training, participation in scientific research projects and publishing papers were the influencing factors (P < .05). CONCLUSIONS: The respondents' core competence needs improvement, especially critical regarding thinking and research ability. In addition, marriage and good or excellent relationship quality are factors that can potentially improve competence. IMPLICATIONS FOR NURSING MANAGEMENT: Targeted interventions for higher core nursing competence need to be implemented, especially focusing on nurses' marital status and emotional support from partners.

Skin-to-skin contact to improve premature mothers' anxiety and stress state: A meta-analysis.

Premature mothers present more anxiety and stress after delivery, which may be caused by mother-infant separation while hospitalised. Skin-to-skin contact (SSC), a mitigating factor for mother-infant separation, can benefit infants and mothers in many ways, but few studies focused on its efficacy on maternal anxiety and stress states. Therefore, this review aims to evaluate the effect of SSC on anxiety and stress. Comprehensive research was conducted in nine databases. Meta-analysis was conducted to investigate the effect of SSC, and subgroup analyses were performed to explain the sources of heterogeneity. Eight randomised controlled trials with 728 participants were included, and SSC significantly reduced the level of anxiety ([standardised mean difference, SMD] -0.72; 95% CI -1.08 to -0.35) and stress state ([SMD] -0.84; 95% CI -1.59 to -0.09). One subgroup analysis revealed that SSC can relieve anxiety if performing SSC no less than 1 h per day ([SMD] -0.94; 95% CI -1.34 to -0.53). Another subgroup analysis suggested that applying SSC repeatedly and lasting less than 1 week ([SMD] -1.49; 95% CI -2.31 to -0.66) or for 1 week to 2 weeks ([SMD] -1.04; 95% CI -1.29 to -0.79) can significantly reduce maternal anxiety level but no significance if lasting over 2 weeks ([SMD] -0.33; 95% CI -0.67 to 0.01). SSC can effectively improve anxiety and stress states among premature mothers after delivery, and not definitive finding presents that only SSC that was performed no less than 60 min could improve postpartum anxiety states, while SSC alone was not as effective when carried out over 2 weeks.

Effect of music intervention on perinatal depressive symptoms: A meta-analysis.

BACKGROUND: Little is known about the effect of music intervention on perinatal depressive symptoms (PDS), especially the effectiveness of specific aspects of the intervention. This meta-analysis aimed to evaluate the effectiveness of music intervention and explore the role of different intervention features. METHODS: Six databases were searched from inception to May 21, 2024, to identify randomized controlled trials evaluating the effect of music intervention on PDS. The Cochrane Risk of Bias (RoB) 2.0 tool was used to assess RoB. RESULTS: The meta-analysis of 10 studies including 988 participants showed that music intervention significantly improved PDS (standardized mean difference (SMD): 0.61, 95% confidence interval (CI): 0.91, -0.32), with statistical heterogeneity among the studies (I2 = 78%). Subgroup analysis showed significant effects on pregnant and postpartum women, and women with or without perinatal complications. Effects were also significant in low- and middle-income countries (SMD: 0.79, 95% CI: 1.16, -0.42), music medicine (SMD: 0.82, 95% CI: 1.17, -0.47), and total intervention length of less than 6 weeks (SMD: 0.85, 95% CI: 1.25, -0.45), but not in high-income countries, music therapy, or total intervention length of 6 weeks or more. Hospital intervention (SMD: 0.86, 95% CI: 1.41, -0.31) showed greater effects compared with home intervention and hospital combined with home intervention. Six studies had a high overall RoB and four had some concerns. CONCLUSIONS: Music intervention is effective in alleviating PDS. Interventions in low- and middle-income countries, music medicine, total intervention length of less than 6 weeks, and hospital intervention may be advisable.

Triple oxygen isotope reveals insolation-forced tropical moisture cycles.

Tropical oceans are the main global water vapor and latent heat sources, but their responses to radiative forcing remain unclear. Here, we investigate oceanic moisture dynamics of the western tropical Pacific (WTP) over the past 210,000 years through an approach of planktonic foraminiferal triple oxygen isotope (Δ'17O). The Δ'17O record is dominated by the precession cycles (~23,000 years), with lower values reflecting higher humidity in concert with higher Northern Hemisphere summer insolation. Our empirical and modeling results, combined with other geological archives, suggest that the enhanced moisture convergence over the WTP largely intensifies changes in the meridional and zonal hydrological cycles, affecting rainfall patterns in East Asia and northern South America. We propose that the insolation-driven WTP moisture dynamics play a pivotal role in regulating tropical hydroclimate.

Effect of psychological interventions on mental health, personal relationships and quality of life of women who have subjectively experienced traumatic childbirth.

BACKGROUND: No targeted review has assessed the effect of psychological interventions on the mental health, personal relationships, and the quality of life of women who have subjectively experienced traumatic childbirth. METHODS: Eight databases were searched from inception to January 2023. Study selection, data extraction, quality appraisal, and data analysis were conducted by two researchers independently. RESULTS: In total, eight studies were included. The results indicated that psychological interventions could effectively alleviate post-traumatic stress disorder (PTSD) symptoms, depression, and anxiety in women who have subjectively experienced traumatic childbirth. The interventions were more effective in alleviating PTSD symptoms than depression or anxiety. The subgroup analysis results showed that the effect of multiple sessions might be better than that of a single session. There was insufficient evidence supporting the effect of psychological interventions to improve personal relationships and the quality of life. LIMITATIONS: Study limitations included the small number of studies included for meta-analysis, substantial heterogeneity, and the retrieval of only studies written in English or Chinese. CONCLUSIONS: Psychological intervention is a promising method for the mental health of women who have subjectively experienced traumatic childbirth, but more studies are needed to confirm the effects. More studies are also required to explore the impact of psychological interventions on personal relationships and the quality of life. Future studies should focus on comparing which specific type of psychological intervention is most effective. Additional investigations should include the potential adverse effects and long-term effects of psychological interventions and details, such as content, process, and timing.

Spontaneous behaviors during breast crawling and factors influencing self-locating mothers' breasts in newborns: A cross-sectional study.

Breast crawling in newborns to propel themselves to their mothers' breasts normally occurs upon skin-to-skin contact with mothers immediately after birth but is often missed by the neglect of hospital staff and insufficient evidence support. Hence, this study described the behavioral characteristics of 135 newborns from China during breast crawling and further explored the factors influencing newborns' self-locating mothers' breasts (measured by whether fail to experience the familiarization stage, initial time and duration of the familiarization stage) using multivariable analysis. The findings supported and extended previous studies that newborns could emerge in nine instinctive stages and corresponding spontaneous behaviors early in life. Moreover, abnormal fetal heart rate during labor appeared to interfere with newborns experiencing the familiarization stage (aOR = 9.27, 95% CI: 1.41 to 61.07, P = 0.021), while using synthetic oxytocin (ß = 5.94, 95% CI: 0.35 to 11.54, P = 0.037), using antibiotics (ß = 11.09, 95% CI: 4.11 to 18.07, P = 0.002), and newborns' gender (ß = -5.69, 95% CI: 11.26 to -0.12, P = 0.045) would alter the initial time of the familiarization stage. Finally, this study proposes evidence-based strategies to prevent abnormal fetal heart rates and improve medication use.

The spatiotemporal extent of the Green Sahara during the last glacial period.

The Sahara Desert, one of today's most inhospitable environments, has known periods of enhanced precipitation that supported pre-historic humans. However, the Green Sahara timing and moisture sources are not well known due to limited paleoclimate information. Here, we present a multi-proxy (δ18O, δ13C, Δ17O, and trace elements) speleothem-based climate record from Northwest (NW) Africa. Our data document two Green Sahara periods during Marine Isotope Stage (MIS) 5a and the Early to Mid-Holocene. Consistency with paleoclimate records across North Africa highlights the east-west geographical extent of the Green Sahara, whereas millennial-scale North Atlantic cooling (Heinrich) events consistently resulted in drier conditions. We demonstrate that an increase in westerly-originating winter precipitation during MIS5a resulted in favorable environmental conditions. The comparison of paleoclimate data with local archaeological sequences highlights the abrupt climate deterioration and the decline in human density in NW Africa during the MIS5-4 transition, which suggests climate-forced dispersals of populations, with possible implications for pathways into Eurasia.

Holocene climate change in southern Oman deciphered by speleothem records and climate model simulations.

Qunf Cave oxygen isotope (δ18Oc) record from southern Oman is one of the most significant of few Holocene Indian summer monsoon cave records. However, the interpretation of the Qunf δ18Oc remains in dispute. Here we provide a multi-proxy record from Qunf Cave and climate model simulations to reconstruct the Holocene local and regional hydroclimate changes. The results indicate that besides the Indian summer monsoon, the North African summer monsoon also contributes water vapor to southern Oman during the early to middle Holocene. In principle, Qunf δ18Oc values reflect integrated oxygen-isotope fractionations over a broad moisture transport swath from moisture sources to the cave site, rather than local precipitation amount alone, and thus the Qunf δ18Oc record characterizes primary changes in the Afro-Asian monsoon regime across the Holocene. In contrast, local climate proxies appear to suggest an overall slightly increased or unchanged wetness over the Holocene at the cave site.

Psychological birth trauma: A concept analysis.

Aim: To define and analyze the concept of psychological birth trauma. Design: The concept analysis method of Walker and Avant was used. Method: Eight databases (PubMed, CINAHL Complete, Cochrane Library, Web of Science, China National Knowledge Infrastructure, Wanfang, VIP Information Chinese Journal Service Platform, and Chinese BioMedicine Literature Database) were searched from inception to July 2022 for studies focused on psychological birth trauma. Results: Of the 5,372 studies identified, 44 ultimately met the inclusion criteria. The attributes identified were (1) women's subjective feelings, (2) intertwined painful emotional experiences, (3) originating in the birth process, and (4) lasting until postpartum. Antecedents were divided into two groups: pre-existing antecedents and birth-related antecedents. Consequences were identified as negative and positive. Conclusion: Psychological birth trauma is a more complex and comprehensive concept than previously thought, and should be regarded as a separate postpartum mental health problem. This study deepens the understanding of psychological birth trauma through a comprehensive concept analysis and also puts forward some suggestions for the prevention, identification, and intervention of psychological birth trauma, which provides a basis for assisting in the identification of psychological birth trauma and provides a reference for the development of rigorous assessment tools and the design of appropriate interventions in the future. Further research is needed to update and refine this concept.
